You did what?
Did you boost it off of a jumper pack or another car? If it was another car, did anything happen to it? You could have possibly fried your ecu (computer) . I know a guy that installed a new battery in his car and hooked it up backwards and that is what happened. Check ALL of your fuses in the fuse box under your hood. I'm not sure which ones could have been blown, if any, but it would be the easiest step and that's what you should start with. Also, check your wires.
